Detailed Implementation

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses a convenient wire feeding mechanism.

[0022] Reference Figure 1 The portable wire feeding mechanism includes a mounting frame 1, on which a wire feeding device is mounted. The wire feeding device includes a wire feeding box 2 mounted on the mounting frame 1, with welding wire wound inside the wire feeding box 2. The mounting frame 1 is equipped with a wire feeding unit for conveying the welding wire from the wire feeding box 2 to the welding point. The mounting frame 1 also has a fixing device for connecting the mounting frame 1 to the welding operator. Therefore, through the fixing device, the wire feeding device on the mounting frame 1 can be connected to the welding operator. When the welding operator moves, the welding device can also move synchronously with the welding operator, facilitating the handling of welding needs at different locations, achieving convenient transport of the wire feeding device, increasing flexibility, and improving welding quality and efficiency.

[0023] Reference Figure 1 and Figure 2 The fixing device includes an annular belt 3 passing through the mounting bracket 1. In this embodiment, the annular belt 3 is made of elastic material. The two ends of the annular belt 3 are connected by a connecting component. The connecting component includes a male buckle 4 at one end of the annular belt 3 and a female buckle 5 at the other end of the annular belt 3 that matches the male buckle 4. The male buckle 4 is inserted into the female buckle 5. Therefore, through the cooperation of the male buckle 4 and the female buckle 5, the annular belt 3 can be detachably connected to the welding personnel, allowing the welding personnel to easily and conveniently load and unload the annular belt 3, making the operation convenient.

[0024] Reference Figure 1 and Figure 2 The wire feeding device includes a first wire feeding wheel 6 and a second wire feeding wheel 7 rotatably connected to the mounting frame 1. The outer edge of the first wire feeding wheel 6 is fixedly connected with a number of anti-slip protrusions. The number of anti-slip protrusions are arranged in a circumferential array along the outer edge of the first wire feeding wheel 6. The anti-slip protrusions increase the friction between the first wire feeding wheel 6 and the welding wire, reducing the possibility of positional deviation during the welding wire feeding process.

[0025] Reference Figure 1 and Figure 2The first wire feeding wheel 6 and the second wire feeding wheel 7 are arranged opposite to each other, and a gap is formed between them. The gap corresponds to the discharge end of the wire feeding box 2, and the size of the gap matches the size of the welding wire. In this embodiment, the size of the gap is the same as the diameter of the welding wire. A guide hose 12 matching the size of the welding wire is installed on the mounting frame 1. The feed end of the guide hose 12 corresponds to the gap. The guide hose 12 limits and guides the position of the welding wire, making it easy for the welding personnel to adjust and control the direction of the welding wire, thereby accurately feeding the welding wire to the welding end. A drive unit for driving the first wire feeding wheel 6 to rotate is provided on the mounting frame 1. The drive unit includes a drive motor mounted on the mounting frame 1. The first wire feeding wheel 6 is connected to the output end of the drive motor through a gear set.

[0026] Therefore, the drive motor is started, and the gear set at the output end of the drive motor drives the first wire feeding wheel 6 to rotate. The first wire feeding wheel 6 is the driving wheel and the second wire feeding wheel 7 is the driven wheel. During the rotation of the first wire feeding wheel 6, the anti-slip protrusions contact and squeeze the outer edge of the welding wire. The anti-slip protrusions push the welding wire during the rotation, and the welding wire in the wire feeding box 2 is transported to the welding end through the guide hose 12.

[0027] Reference Figure 1 and Figure 2 A connecting frame 8 is hinged to the mounting frame 1, and a second wire feeding wheel 7 is rotatably connected to the connecting frame 8. A limiting unit for fixing the position of the connecting frame 8 is provided on the mounting frame 1. The limiting unit includes a connecting seat 9 provided on the mounting frame 1, a limiting rod 10 is hinged to the connecting seat 9, and a limiting groove 14 matching the size of the limiting rod 10 is provided on the connecting frame 8. The limiting rod 10 is inserted into the limiting groove 14, and a limiting block 11 is installed at the end of the limiting rod 10 away from the connecting seat 9. The free end of the connecting frame 8 is restricted between the limiting block 11 and the connecting seat 9.

[0028] Therefore, when the connecting frame 8 rotates relative to the mounting frame 1 along the hinge point, the second wire feeding wheel 7 moves synchronously with the connecting frame 8, making the position of the second wire feeding wheel 7 movable and more flexible. After the second wire feeding wheel 7 moves to the appropriate position, the welder rotates the limiting rod 10, so that the limiting rod 10 is inserted into the limiting groove 14. At this time, the end face of the limiting block 11 facing the connecting frame 8 abuts against the connecting frame 8, thereby fixing the position of the connecting frame 8. The limiting groove 14 plays a limiting role in the position of the limiting rod 10, reducing the possibility of the limiting rod 10 shifting position.

[0029] Reference Figure 1 and Figure 2A guide tube 15 is installed on the connecting seat 9. The inlet end of the guide tube 15 corresponds to the outlet end of the wire feeding box 2, and the outlet end of the guide tube 15 corresponds to the wheel gap. In this embodiment, the guide tube 15 is formed by spirally coiling elastic wire, and the diameter of the end of the guide tube 15 facing the wire feeding box 2 is larger than the diameter of the end away from the wire feeding box 2. That is, the end of the guide tube 15 facing the wire feeding box 2 is flared. The guide tube 15 guides the position of the welding wire and limits the position of the welding wire at the output end of the wire feeding box 2, reducing the possibility of position deviation when the welding wire is fed from the wire feeding box 2 to the wheel gap, and improving the stability of the welding wire feeding.

[0030] Reference Figure 1 and Figure 3 The mounting bracket 1 has several mounting holes 13. Using the mounting holes 13, the welder can also fix the mounting bracket 1 to the welding equipment by bolt connection, realizing multiple installation and use methods of the convenient wire feeding mechanism, which is more flexible.

[0031] The implementation principle of this embodiment is as follows: The annular belt 3 is detachably connected to the welder via the interlocking of the male and female buckles 4 and 5. When the welder moves, the convenient wire feeding mechanism can also move synchronously with them, facilitating welding needs at different locations. Subsequently, the drive motor is started, and the gear set at the output of the drive motor drives the first wire feeding wheel 6 to rotate. During rotation, the anti-slip protrusions of the first wire feeding wheel 6 contact and press against the outer edge of the welding wire, pushing the welding wire through the wire feeding box 2, sequentially passing through the guide tube 15, the wheel gap, and the guide hose 12 before being delivered to the welding end. The fixing device allows the wire feeding device on the mounting frame 1 to be connected to the welder, enabling convenient handling of the wire feeding device, increasing flexibility, and improving welding quality and efficiency.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
